Репликация Tomcat 7 — разные машины

У меня есть 2 кота:

1) 10.0.50.35

2) 10.0.110.31

10.0.50.35 сервер.xml:

<Engine name="Catalina" defaultHost="localhost">

 <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
             channelSendOptions="8">

      <Manager className="org.apache.catalina.ha.session.DeltaManager"
               expireSessionsOnShutdown="false"
               notifyListenersOnReplication="true"/>

      <Channel className="org.apache.catalina.tribes.group.GroupChannel">
        <Membership className="org.apache.catalina.tribes.membership.McastService"
                    address="228.0.0.4"
                    port="45564"
                    frequency="500"
                    dropTime="3000"/>
        <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                  address="auto"
                  port="4000"
                  autoBind="100"
                  selectorTimeout="5000"
                  maxThreads="6"/>

        <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
          <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
        </Sender>
        <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
        <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
      </Channel>

      <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
             filter=""/>
      <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

      <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
                tempDir="/tmp/war-temp/"
                deployDir="/tmp/war-deploy/"
                watchDir="/tmp/war-listen/"
                watchEnabled="false"/>

      <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
      <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
    </Cluster>

А вот и сервер 10.0.110.31.xml

<Engine name="Catalina" defaultHost="localhost">

 <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
             channelSendOptions="8">

               expireSessionsOnShutdown="false"
               notifyListenersOnReplication="true"/>

      <Channel className="org.apache.catalina.tribes.group.GroupChannel">
        <Membership className="org.apache.catalina.tribes.membership.McastService"
                    address="228.0.0.4"
            bind="10.0.50.35"
                    port="45564"
                    frequency="500"
                    dropTime="3000"/>
        <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                  address="auto"
                  port="4000"
                  autoBind="100"
                  selectorTimeout="5000"
                  maxThreads="6"/>

        <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
          <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
        </Sender>
        <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
        <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
      </Channel>

      <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
             filter=""/>
      <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

      <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
                tempDir="/tmp/war-temp/"
                deployDir="/tmp/war-deploy/"
                watchDir="/tmp/war-listen/"

      <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
      <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
    </Cluster>

10.0.110.31 запускается, а 10.0.50.35 не запускается со следующей ошибкой:

Я ничего не знаю о кластеризации Tomcat, но должна ли быть запись bind=10.0.110.31 для вашего сервера 10.0.50.35?   -  person Jaydee    schedule 30.10.2013

Уберите "авто" из

<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                  address="auto"
                  port="4000"
                  autoBind="100"
                  selectorTimeout="5000"
                  maxThreads="6"/>

и укажите свой локальный адрес.

Несколько предложений:

Во-первых, убедитесь, что многоадресная рассылка правильно включена на ваша система.

Во-вторых, убедитесь, что ваша JVM сначала пытается привязаться к адресу IPv4 (а не к IPv6). Сделайте это, добавив следующее в JAVA_OPTS в catalina.sh в каталоге bin tomcat:

JAVA_OPTS="-Djava.net.preferIPv4Stack=true"
